Kale: Now Available at McDonald's. True Story

Quick, think of the last place you'd ever expect to order kale. OK, no, we're not talking about Dairy Queen, but close enough—McDonald's has announced it's adding breakfast bowls featuring the leafy greens to its menu.

Are pigs flying yet? After all, it was just four months ago that the chain ran a Big Mac ad saying its classic burger "Will never be kale." The new A.M. offering, which is selling for about $4, won't be served nationwide just yet; you'll have to visit golden arches locations in Southern California at this point if you want to give it a taste test.

Is this addition the latest news of a fast-food chain aiming to help its eaters get healthier? It seems a pretty obvious attempt to attract a new kind of nutrition-conscious customers, amid constant talk of the fast-food giant's slumping sales. (A report in February noted a 4 percent drop in sales from a year earlier.) A market-research report release this spring stated that "McDonald's clearly aims to raise consumers' perception of the quality of its food. Adding kale to the menu in some way could help be a step in this direction."

If nothing else, maybe it's one thing on the menu you can super-size without feeling too guilty. Next up: Kale Shamrock Shake?
